How to add a view's Setonclicklistener

1) The first, but also the longest-to-see method of addition (click on the button for example)

1 Button btn = (button) Findviewbyid (R.id.mybutton);
2 btn. Setonclicklistener (New View.onclicklistener () {
3 Public         void OnClick (View v) {
4//do Something
5         }
6     });

2) Second, the following method is slightly simpler than the previous one, allowing multiple buttons to share a single listener. To control the response to different button click events via the switch:

1 Button btn = (button) Findviewbyid (R.id.mybutton);
2 Button btn2 = (button) Findviewbyid (R.id.mybutton2);
3 Btn.setonclicklistener (handler);
4 Btn2.setonclicklistener (handler);
5 View.onclicklistener handler = View.onclicklistener () {
6 Public         void OnClick (View v) {
7             switch (V.getid ()) {
8                
9//do Something
Ten break                ;
11                
//do something
Break                ;
+             }
     }

3) Third, directly clicklistener bundle the views element in the XML layout, the listener method defined in the program requires a parameter with a view type:

1 <?xml version= "1.0" encoding= "Utf-8"?>
2 <linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"
3     android:orientation= "vertical" android:layout_width= "fill_parent"
4     android:layout_height= "Fill_parent" >
5     <textview android:layout_width= "Fill_parent"
6         android:layout_height= "wrap_content" android:id= "@+id/text"
7         android:text= "@string/hello"/>
8     <button android:id= "@+id/mybutton" android:layout_height= "Wrap_content"
9         android:layout_width= "wrap_content" android:onclick= "Mybuttonlistener" ></Button>
Ten </LinearLayout>

Java code:

1 Button btn = (button) Findviewbyid (R.id.mybutton);

3 public void Mybuttonlistener (View target) {
4//do Something
5     }
